AI Technical Summary

Benefits of technology

The system reduces the time required for attaching and detaching workpieces, minimizes waiting times, and enhances machining efficiency by enabling precise control of holding and releasing operations, allowing for accurate machining of various workpiece shapes and sizes.

Problems solved by technology

However, in the securing device of hydraulic type or pneumatic type, a workpiece is held or released without any fine tuning of the position of the piston.
This causes the claw part to move broadly, and increases working hours.

Embodiment Construction

[0031]A machining system in an embodiment will be described with reference to FIGS. 1 to 14. The machining system in the present embodiment is provided with a machine tool for machining a workpiece using a predetermined tool, and a robot for attaching and detaching a workpiece to and from the machine tool.

[0032]FIG. 1 shows a schematic perspective view of a machining system in the present embodiment. In a machining system 100 in the present embodiment, a workpiece 9 to be machined by a machine tool is replaced by a robot 2. The machine tool in the present embodiment is a numerically-controlled machine tool. Namely, the machine tool can automatically machine the workpiece 9 based on a preliminarily prepared machining program. The machine tool in the present embodiment is provided with a first securing device 4 secured to a table 11. The workpiece 9 is secured to the table 11 via the securing device 4.

[0033]The machining system 100 is provided with the robot 2 which attaches the unmac...

Abstract

A machining system is provided with a machine tool including a securing device for securing a workpiece, a robot for attaching the workpiece to the securing device, a hand attached to a tip end of an arm of the robot, and a control device for controlling the machine tool, the robot, and the hand. The securing device includes holding members for holding a workpiece, and holding member drive motors for moving the holding members.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a machining system provided with a machine tool and a robot for attaching and detaching a workpiece.[0003]2. Description of the Related Art[0004]In recent years, a machining system provided with a robot for attaching and detaching a workpiece to and from a machine tool has been used. In the machining system, the robot introduces a workpiece to the machine tool, and the machine tool machines the workpiece. After the machine tool finished machining the workpiece, the robot discharges the workpiece from the machine tool.[0005]Japanese Unexamined Patent Publication No. 61-125752 discloses that a hydraulic cylinder or a rotary cylinder embedded in a chuck device of a machine tool activates an actuator, and that the activation of the actuator causes a plurality of liners to move to automatically attach or detach a workpiece to or from the chuck device.[0006]When a robot attaches or detaches a ...
